概要

The 8440258-46 is an 8-output synthesizer optimized to generate Ethernet clocks. The device will generate 125MHz and 25MHz clocks from a 25MHz crystal with a very good jitter performance. The 8440258-46 uses Renesas' third-generation low phase noise VCO technology and is packaged in a small, 5mm x 5mm VFQFN package.

  • Four differential LVDS outputs at 125MHz
    • Two LVCMOS/LVTTL single-ended outputs at 125MHz
    • Two LVCMOS/LVTTL single-ended outputs at 25MHz
  • Selectable crystal oscillator interface or LVCMOS/LVTTL single-ended input
  • RMS phase jitter at 125MHz, using a 25MHz crystal
    (1.875MHz to 20MHz): 0.5ps (typical)
  • Full 2.5V supply mode
  • 0 °C to 70 °C ambient operating temperature
  • Lead-free (RoHS 6) packaging
